To all 'whom it may concern.' y

Be itknown that we, DAN LA COUR and CECIL VILHELM SCHOU, subjects of the Kinor of Denmark, residing at Cliailottenlundj, near Copenha en, Denmark, and Copenhagen, Denmar respectively, have invented new and useful Vaporizing-Starters; and we do hereby declare the following to be a full, clear, and'e'xact description of the same.

The invention relates to an ap aratus for speedily causing liquid fuel suoi as kero sene, fuel oil, etc., to evaporize, and especially aims at a speedy and convenient starting of combustion engines which work with such fuel, and at igniting such .burners which demand a previous heating, which when effected by ineans of a. flame, takes a comparatively long time and is sometimes niadeimpossible for instance on account of wind when such lamps are-used in the free Such an apparatus consists general] in aimember of. well conducting metal suc as co per, which is adapted for accommodatin a eatin cartridgqwhich through' chemical reaction between the 'substances ofwhich 'it consists is able to develop a. considerable guanti ty of heat in a small space, and which is shaped in such amanner that it conducts the heat to the place where it is to Vbe utii' vlized for. evaporizing of'the liquid fuel in question.

Different modifications of the invention are sli-own in the drawing, where- Figure 1 shows a longitudinal section of the apparatus adapted for being arranged on u Cmi'ibustion engine,

llfig, i', a different modification and Fig. 3 a modification of the apparatus for use in speedy stur-ting of an ordinary kerosene-soldering-lfunp.

ln l'ig. .l a. designates a cop er member 'having n free outer' surface L un a free surface c'iiount'l in the combustion Chamber of the engine. The 'mei'uber a is by means of the ring d in a suitable inani'ier secured on the combustion chamber, which depending on the cireumslaiites may bc closed by the cylinder cover may consist of a socalled glowhead- The packings f which consist of asbestos or the like, at one time effect .tightness and heat insulating.

The injection nozzle g is directed toward the liee sur face. When the motor is to be started, :i lient cartridge h is put on the surface b and i nited, whereupon an insulating cover lo is the member a will become so hot'that the motor can be started and work.

The use of copper for the member a 'is of importance, because the quantity of hea't put over, and in the course of a'few seconds given off by the same, will7 owing to the liquid fuel being in'ected against a comparatively small sur ace, practically instanta-l neously be substituted by admission of heat from the neighboring parts of the said mem ber. A member ,of iron wou1d. not;or but badly, be empioyabie.

If a cartridge containing l'aluminium powder and iron oxid be used, itfis appropriate to protect the insulating cover lc by means of a copper plate m.

Fig. 2 shows asimilar modification, lmeant for` being introduced fronti the side'V but otherwise acting in a manier quite similar to that shown in Fig. l. fyi

' Fig. 3 shows oneof the ordinary evaporizing burners for kerosene, in which. the

evaporizing *of the `kerosene introduced heated to a temperature above the' boiling point of the kerosene, and this is according to the present inlvention effected by some part of thgtibe through which the kerosene is introduced and in which the evaporizing is to take place arian `ng.a coppermember 0 wh ich can accomr'uo ate a. heat cartridge and transmit the heat to the tube.

In a. similar manner the a paratus can be used for starting the Well npwn kerosene incandescent li ht burners.

AHaving thus lly described'our invention, we claim as new and desire to'secure by Letters Patent:

l. Device for speedil)7 evaporizing liquid fuel in a closed space comprising a member; of a well conducting metal having a concave outer surface adapted to hold and be heated by a heating ca'rtridge the said member being adapted. to convey the heat to a place in the said closed space where the evaporizing .is to be eected.

2. Device for speedily evaporizing li uid 'fuel in n closed space comprising amem er of a well conducting metal having a concave outer surface adapted to hold and be heated by ahenting cartridge thesnid member msssaid closed space and means for insulating 10 ing through un opening 1n the wall o the the Seid member from the seid wall.
